Application led October 29, 1927. Serial No. v229,783

My` invention relates toa new and improve-d form of pumping device for automatically pumping water out of cellarsor the like when watcrenters the place which must be ykept dry, or when the Vlevel of the water in .said place exceedsa certain predetermined height..

One of the objects of my invention' is to provide a devicevwhicli shall be simple and automatic in operation.

Another Object of my invention is to provide a device which will be of simple, efficient and compact construction.

Other' objects of my invention will be set forth in the following description and drawings which illustrate a preferred embodiment thereof, lit being understood ythat the above general statement-of the objects of my invention is intendedmerely to generally eX- plain the same Vand not to limit it in any manner.

Fig. 1 is a side elevation of the device embodying my invention.

Fig. 2'is a View similar to Fig. 1, certain of the parts being omitted. This figure shows the float in the upper position.

F ig. 3 is a detail View partially in section showing the switch for controlling the electric motor.

Fig. 4 is a sectional view on the line lA-4 of Fig. 3. Y

The device comprises a frame consisting of four uprights 10 made of anole irons or other suitable material. A centrifugal pump 13 is securedto the four frame members 10 adjacent the bottoms thereof. The four frame members 10 are connected at the tops thereof V to a stand 11, by means of rivets or bolts 12.y

An electric motor M Vis mounted upon the stand 11 and this is provided with a power cable 26 of the ordinary t-ype which is connected to the switch casing 25. l y

The kvertical shaft S of the motorM 1s directly connected to the rotor of the pump 13 which has lateral inlets into which the water ows, as indicated by the arrows at the bottoms of Figs. 1 and 2. The pump l13 is provided with an outlet 14 to which a hose 15 can be suitably connected.

' -A float 16 is provided with perforated lugs rod 2O is provided with a lower collar 18 ad justably secured thereto by a` clamping screw,

`and it is also provided with an upper collar 19 also adjustablyconnected thereto by 4a clamping screw. 'The f'ioa't 16 normally rests in the position shown in Fig. 1.,Vv However, the float 16 Acan be raised'by water until' itsv upper lug 17 presses upwardlyupon the collar 19 so as to upwardly actuate the switch rod 20. The switch rod20 is providedv with the connecting membery 22 by means of which it is pivotally connected tothe switch lever 23 which is pivotally connected tothe side of the lswitch casing 25 at 24. As shown more par-' ticularly in Figs. 3 and 4, the switch lever 23 has a laterally bent arm provided with a slot 28 into which the head 27 ofthe switch finger y projects. The switch S is of the ordinary snap type. Hence-,when the fioat16 is moved into circuit and when the float 16 moves to its lower position (shown in Figjl) y the supply vthe device below the floor level o the said cellar.- The water in the cellar moves the float 16 to the upper position shown inV Fig. 2.

The centrifugal pump is thereby thrown into operation because current is fed to the motor M and the switch ofthe motor M remainsinv the operative or circuit-closing position until the iioat 16 can bear uponthe lower collar18` with sutlicient force to overcome the resistance of the spring 30 of the switch and thereby move .the rod 2O into its lower position.

Vhen this occurs the level of the water is only slightly above the level ofthe inlets of the pump 1 v The switch rod 2O passes through a guide 21 connected to the pump casing.

I have shown a preferred embodiment of my invention, but it is clear that numerous changes and omissions could be made without departing from its spirit. Y U f 1. Apumping device comprising va pump mounted in a frame, an electric-motor connected to the said pump and adapted to operate the same, a snap switch having a spring and adapted to l. control the saidmotor, .a switch rod connected to the said snap switcl:l and adapted to operate the same, and a vertically movable float'slidable with respect to said switch rod and" adapted to operate the said switch rod at predetermined points of the vertical movement-of the said Hoat', said ioo "ated in said frame and slidable float beingl therein.

2. A pumping device comprising a frame,

a rotor pump connected to the said frame, an

electric motor connected to the said frame and having a shaft Which is connected to the rotor of the said pump, a switch for the said'motor connected to said frame, said switch having a switch rod and a fioat connected tothe said switch and adapted to operate the same, said fiot being slidable with respect to said switch ro i w 3. A pumping device comprising a frame having a plurality of angle irons to which an electric motor 'is connected, a rotor pump connected tothe said frame, the rotor of said pump being connected to said motor, a float located Within said frame slidably mounted between said-angle irons and guided in its movement by the 'faces of the said angle irons, a vertically movable switch rod having a pair of collars connected thereto, said collars being located one above the other, the said `float having a pair of perforated extensions located intermediate the said collars, the said switch rod passing through the said perfo rated extensions, and a switch to which the irons, a vertically movableaswitch rod having a pair of collarspeonnected thereto, said collars being `located one above the; other, the g said float having a pair of perforated exten sions located intermediate the said collars, the said switch rod passing through the said lperforated extensions, and a switch to which the said switch rod is connected, the said switch being adapted to control the said electric motor, the shaft of the motor being substantially parallel to the central axis of the frame and the pump being substantially per pendicular to the said central axis.

\ In testimony whereof I alix my signature.
